Shows how the sun's magnetic field evolves over three solar cycles using maps of the solar surface magnetic field obtained by the National Solar Observatory. Begins with a series of magnetic images obtained over a 27 day rotation of the sun ans shows how a magnetic map of the surface is peeled off the sun.

|Small Dynamic Events on the Sun Captured by Hinode|
The X-ray Telescope on the Japanese/NASA mission Hinode has been observing the full Sun for an extended period. In this movie significant small-scale dynamic events can be observed as well as the slow maturation of many active regions now visible on the solar disk. Hinode is joint JAXA/NASA mission to study the connections of the Sun's surface magnetism, primarily in and around sunspots.

|Solar Sail Readies for Early Warning Mission|
NASA's Solar Sail project, directed by L'Garde of Tustin, Calif., plans to take this innovative technology beyond Earth's orbit. The spacecraft will have a "sail" one quarter the size of a football field and park in a pseudo LaGrange point closer to the sun to double the current warning period for dangerous solar flares. Slated for launch in late 2014, the instrument aboard the solar sail craft will use the sun's photon radiation to gently offset the corresponding pull of the sun's gravity.

|Solar Magnetic Fields and Sunspots Explained|
This video shows the association of magnetic fields with sunspots and coronal loops. Begins with images in white light from the ESA/NASA SOHO mission MDI instrument showing the presence of sunspots and the 27-day rotation of the sun.

|Solar Eclipse May 20th as Seen by Hinode|
An annular solar eclipse took place in the late hours of May 20th, into the 21st, and was visible from the ground in southern China, Japan, and the western United States. Hinode is in a low-Earth (630km altitude - about 400 miles) sun-synchronous polar orbit that permits nearly continuous observations of the sun and was in position to capture images of the solar eclipse.

|Ikeya-Murakami: The New Comet on the Cosmic Block|
This video shows the motion of Comet Ikeya-Murakami on Nov. 13, 2010, captured with a New Mexico-based telescope operated remotely by NASA's Marshall Space Flight Center. The images were taken near dawn and show the comet's movement over a period of 45 minutes. Each exposure was three minutes in length, and the faint angled streak around 0:10 in the animation is a satellite trail. At the time of these images, the comet was some 229 million miles away from Earth...

|Venus in Transit - Impact on Space Science with Jim Spann|
One of the most uncommon celestial phenomena, a solar transit by the planet Venus, will occur Tuesday evening. The Marshall Center will help build excitement for the rare event with a Lunch & Learn at 11 a.m. on Monday, June 4, in Morris Auditorium in Building 4200. Marshall scientist, Dr. Jim Spann will host the informative session. Participants will learn more about the phenomenon, which occurs in a pattern repeated every 243 years, with pairs of transits eight years apart...
